For all those who want to influence more than just their ride height. ST XA Coilovers deliver the look you need through a wide range of height adjustment. With an extensively adjustable damper setup, you can precisely adjust the driving behavior of your car to achieve enhanced road control without a compromise in comfort. ST XA Coilover kits deliver precise adjustment to your ride height and look of your car. We manufacture the adjustable spring perch made of durable and friction-optimized polyamide composite material with a stainless steel insert. Thanks to the composite material corrosion is prevented between the strut and perch ensuring long lasting height adjustability while the stainless steel insert provides strength and confidence! ST XA Coilovers come preset to our factory recommended damper settings, the same configuration we test them at on our KW shock dynos before they go into your box. The 16 distinct clicks of adjustable rebound damping allow you to refine the driving dynamics with a simple turn of the adjustment knob. Each kit includes a detailed damper setup manual making it easy to reset to our recommended setting at any time. Whether your preference is comfort, sportiness, or something in between; ST XA puts the finer details of the driving dynamics in your hands. Galvanized zinc coated steel struts optimize corrosion protection for long lasting use. We add a dust protection system to prevent unwanted dirt and particulate from coming in contact with the hardened chrome piston rod or getting into the valve packs. We reinforce the system with a multi-layered pressure resistant sealing package, mono block guide system and a low friction piston band which works inside the pressure resistant internal damper housing.
- Elastomer Bump stop with integrated dust protection system prevents water and dirt particles reaching the piston rod and seals. The highly resilient bump stops act as dynamic load limiters while maintaining ride quality and durability.
- Composite spring perch made from wear-resistant, friction-optimized polyamide composite with an embedded stainless-steel insert. The polyamide composite prevents oxidation while the stainless-steel insert maximizes strength.
- ST coilovers are built by hand by the experts at KW in Fichtenberg, Germany. Each damper is tested on a shock dyno to verify it's making the proper forces before being put into the ST box.
- Seamless Ride Height Adjustment - ST's composite spring perch and unique trapezoidal thread pitch make ride height adjustability a breeze so you can dial in your preferred look
- ST XA coilovers feature adjustable rebound damping which puts you in control of how comfortable or sporty your car feels.
- Zinc galvanized steel housing for improved resistance to corrosion.
- 5 Year Limited Warranty - Unlimited Mileage
- Made in Germany

Perfect chair!
Color: Cream
I love this chair! Was hesitant to buy due to the price being a bit more than I wanted to spend, but I work from home and have terrible posture from sitting at my desk all day, so I needed something that would be conducive to helping me sit up properly. I put the chair together myself, it was heavy but overall pretty easy to do. The tools provided worked great and the directions were clear. Aesthetically, it’s a lovely neutral color and everyone who has seen it so far has complimented me and on how nice it is and how comfortable it looks — Indeed it’s a very expensive looking chair. The first time I sat on it I wasn’t sure if I was going to like it….maybe something about the lumbar support seeming to protrude too much? At any rate, I gave it a couple of days and I absolutely LOVE it. I can already feel my posture improving, no backaches and I’m perfectly comfortable all day long. I’ve had it for a couple weeks now and couldn’t be happier. It seems to be very well made, so I’m confident it will last a very long time and be worth the price. I HIGHLY recommend this chair!

UPDATE: DEFECTIVE… it was a Great chair... a bit short for tall people!
Color: Cream, Color: Cream
I purchased this chair four years ago and really liked it. However, when it was damaged during a move, I attempted to replace it. Unfortunately, the replacement chair had a construction issue that had been repeatedly mentioned in numerous comments spanning over a year at least. This defect prevents the chair from being completely assembled, rendering it unusable (screw holes don’t line up). Amazon has failed to address this issue by removing these defective chairs from its inventory. You won’t be aware of this problem until you’ve almost completed assembling the chair. At that point, you’ll have to disassemble it, rebox it, and return the box to UPS. This is an incredibly inconvenient process, and Amazon must take immediate action to rectify this issue before anyone considers purchasing this chair again.
Old review from 2023:
Based on someone else's review, it would seem that this chair is perfect for average-height people but less great for those of us who are a bit tall or (according to her) a bit short. I'm 5'9 with most of my height in my legs. I like a chair to be tall enough that my legs can be straight to the floor from my knees to my feet and still have support under my knees. This chair is too short for that, even at it's highest setting, but it can be fixed with a simple replacement of the gas lift cylinder for a mere $20 (search for gas lift cylinder on Amazon). And the extra $20 is worth it because other than that one issue, this chair is great. My first experience with this chair was at work when the firm replaced all of our desk chairs. I loved it so much that I bought it for myself when I went into private practice. The lumbar support hits in just the right spot and moves with your body as you lean in and out. I love the cream color, and the seat is padded nicely. I especially love the liftable arms. I sit at my desk for 8+ hours straight 5-6 days a week, and I never have body pain-- Granted, I am only 36, but I have definitely experienced this with other office chairs that claimed to be "ergonomic". With a simple lift cylinder replacement and a movable standing desk (which I never actually stand at), I can finally sit at my desk without my knees hitting the underside of the desk or my legs having to be extended out to have support under my knees. These two things mean that I don't slump at my desk anymore, and my neck and back thank me! :)

Good but not great. Limited adjustment
Color: Cream
Chair looks great and is very comfortable and well made. I took stars off because a couple of issues that I can’t live with and will require me to buy another chair.
The chair does not rise high enough. Unlike other office chairs, I feel like I’m a little kid at the adult table(I’m 5’10” male).
The most annoying feature is the chair back angle isn’t adjustable so I’m always at a slight recline. I have to place a pillow behind me to look like I’m not falling asleep while on camera. Suprised there isn’t an adjustment for that.
I would have discovered all of this if I was able to try it out before hand but the mass positive rating don’t mention these issues.

COMFY CHAIR GOOD SUPPORT
Color: Dark Brown
So I needed an office chair because the one that I had wasn't really helping my back any. And it just didn't have enough cushion on the chair because when you want to sit for hours at your desk you want to be comfortable. So I took a chance on buying this chair. I thought the color was good and the price was right but I was still a little nervous because it said put together. So I got it right away only took 3 days. And the directions for pretty easy there were a couple of spots that I think we're out of order because you had to kind of play around with the screws going into the holes from the arms but I think if I were to get another chair like this I would probably do it my way because it's pretty self-explanatory but I followed the directions that came with the chair. And hey I'm 65 years old and I put this chair together. It's nice it's sleek and oh my God is it comfortable!!! Right where my lower back and sciatic is I get the support and it just feels good and I know that if I have to be at my desk for 3 or 4 hours I'm going to be comfortable. I highly highly recommend getting this chair.
The only issue that I had was the driver did not leave it on my porch. I had ordered a Vizio TV a couple months ago and the driver brought it up to my porch. So I just had to go out and take two steps bring it into the house I really appreciated that.
This driver didn't even come through the gate and there is no signs of any dogs because there aren't any. So this driver just left this giant heavy box it was about 35 lb in front of the garage where it was very visible from the road. And I had a dragon to my front door it was heavy I did not like that at all. But it wasn't damaged or anything and I do love the chair. I just don't like what the driver did.
